UV Disinfection and Chemical Treatment

Today, when water is very valuable, ecological conscience inspires the idea that waste water we can treat and use again. Post treatment in water treatment is disinfection and it can be: chemical treatment (chlorination) and UV treatment.

CHLORINATION

Many of waste water treatment systems use chlorination like disinfection method. Chlorination is process of adding of chlorine compounds in water, to remove all of microorganisms and on that way we can block their grown and division. For water disinfection we can use chlorine-dioxide, gaseous chlorine, sodium-hypochlorite and calcium-hypochlorite.

UV DISINFECTION

UV disinfection is effective way for moderation of all bacteria, viruses and spores, including pathogenic who has immunity on chlorine, doing photochemical changes inside cells of organism.
For UV disinfection we are using lamps who work on wavelength from 180-1370 nm.
